What would cause my low starting voltage?

Well I asked a question about my TS chip not always working and I had to shut down the truck and restart and it would work. The answer was the voltage is too low for the chip at start up.

So, what besides batteries would cause this? The batteries are less then two years old I know it could be them but I would like to think that its not ha.
Could it be the starter?
not the best with stuff like this so any help would be great, I hate having to shut the truck down when its cold to get the chip to work!

Well yeah I guess that could be it but the voltage drop info was given to me by TS Performance so I was going with that. But I will have the chip out shortly to send into TW for a reburn so I will clean up the contacts.

I also put a multimeter on the batteries and cranked the truck and it did drop below the recommended voltage for a split second. I guess I'll the best bet is to get my wallet out and start replacing stuff?

Ill tell you what happened to me and it might help. I had a shop install an alarm/remote start system and somehow(cant prove it) they messed up my alternator. It was still charging but not at full power, so on start up my batteries were dropping down to about 10 volts and with the alternator not charging at full power it would cause the remote start to shut the truck back off because of low voltage around 10 volts. So you might want to check your alternator. Someone told me they think the voltage regulator on the alternator was messed up.
